but we do want to get to the breaking news out of Ferguson. Video coming in. Heavily armed officers on the streets as at least one store was looted. Tear gas also fired at the protesters. This Friday night flare-up comes after what had been 24 hours of relative calm by then a rush of emotion. Police released this videotape allegedly showing Michael brown rob a convenience store. Moments before he was shot and killed by an officer. Supporters calling this an attempt to smear the victim. Team coverage and we start with Alex Perez who is on the ground in Ferguson. Alex, good morning to you. Reporter: Hey, good morning, Dan. We actually had to switch locates because of safety reasons, now those protests began peacefully but overnight turned violent. As many as 200 people coming head-to-head with police. Overnight the shaky calm in Ferguson is shattered by more violence and looting. Protesters blocks streets throwing bottles. Police in armored vehicles and carrying military-style rifles responding with smoke bombs. This coming hours after the name of the officer that shot and killed unarmed teenager Michael brown was revealed. The officer that was involved in the shooting of Michael brown was Darren Wilson. The Ferguson police chief naming officer Darren Wilson after a week of mounting pressure to identify the officer. Officer Wilson is a six-year Rhett van of the force and has had no prior disciplinary incidents at this home no sign of Wilson. Police confirming Wilson has been relocated after a number of threats. Authorities Friday also releasing in liquor store surveillance video. Police say this shows Michael brown, 15 minutes before the shooting. Allegedly taking a box of cigars without paying. Then shoving the manager who went after him. Overnight that very liquor store becoming the scene of violence and looting and protesters seen exiting the store with lottery tickets. Family members calling the surveillance video a distraction. It infuriated us and it just added to the distrust. The issue is when Michael brown raised his hand and was kneeling to surrender why did the police officer continue to fire and kill this young man? Police also saying the officer who shot and killed brown didn't know brown was a suspect in a robbery and had initially stopped brown for blocking traffic. Because they were walking down the middle of the street. Hands up don't shoot. Reporter: And those protesters expected back out here again today. Of course, police keeping a close eye on all of this and calling on those demonstrators to remain peaceful. Paula. Alex, thank you. Now to the man in charge of the crisis, captain Ron Johnson, calling for calm as the leader of security operations and assuring the community that he wants justice just as much as they do. ABC's Steve osunsami has more. A bunch of hugs and conversations so that's what you'll see from me. Reporter: Thursday the governor gave him the job of keeping the peace. Today we woke up and we're all still happy and we're all still hugging and we're all still communicating. They're asking for answers and I'm guaranteeing I'm getting to get them the answers.

In the middle of march against police there he was side by side with the demonstrators. He says he doesn't want his neighbors to ever fear his badge. We need to make sure justice is done.
